I'm using the official WiFi shield on top of Uno R3 and I'm trying the examples provided in the WiFi library, but unfortunately the serial says that the "WiFi shield not present"
Would anyone please tell me how to solve such a problem? and is there anything missing in the code that I should add?
Regards
here's the codde
============================================
#include <spi.h>
#include <wifi.h>
char ssid[] = "wifiname"; // your network SSID (name)
char pass[] = "wifipass"; // your network password
int keyIndex = 0; // your network key Index number
int status = WL_IDLE_STATUS; // the Wifi radio's status
void setup() {
//Initialize serial and wait for port to open:
Serial.begin(9600);
while (!Serial) {
; // wait for serial port to connect. Needed for Leonardo only
}
// check for the presence of the shield:
if (WiFi.status() == WL_NO_SHIELD) {
Serial.println("WiFi shield not present");
// don't continue:
while (true);
}
// attempt to connect to Wifi network:
while ( status != WL_CONNECTED) {
Serial.print("Attempting to connect to WEP network, SSID: ");
Serial.println(ssid);
status = WiFi.begin(ssid, keyIndex, pass);
// wait 10 seconds for connection:
delay(10000);
}
// once you are connected :
Serial.print("You're connected to the network");
}
void loop() {
// check the network status connection once every 10 seconds:
delay(10000);
Serial.println(WiFi.status());
}

Hello friend of dfrobot I want to ask for a help with this shield I with this module I can be linked to a router that has interner osea the ones that we have in the house the ones that give service of wifi is to send data either to a server can or not Can you help me if you can help me code,
Sorry if this is badly written use translate from google I'm Colombian
JaneYu can i connect dfrobot wifi shield to arduino cloun?? and what is the difference between arduino wifi101 shield and dfrobot wifi shield???
JaneYu No sample code for the arduino cloud now. And both Arduino uno wifi and industrial 101 are different. UNO wifi is based on ESP8266, and industrial 101 is almost same to the Arduino yun. Anyway, this is a serial wifi device. just serial communication.
i have this wifi shield connected on arduino mega board and i need to send data to a cloud server any free cloud server. can you provide me with code or sample how to send data to a cloud?
JaneYu hello i have a dfrobot wifi shield connected to arduino mega. and i want to connect it to cloud so i can send data i tried many codes but none of them helped, can you provide me with a code or sample of how to send data from this shield to a cloud thanks in advance
JaneYu Hi. For the time being, there is no demo for or example code to upload data to cloud for this module.
However you can try using this tutorial as reference. You need do some modification like changing "WidoClient.fastrprint()" to "Serial.print()". And it is recommended to use Serial1 on mega board for easy debugging. Hope it will help you.

You can also post your request on our forum. Maybe others can help you.
Hi,
I am totally new in this wifi shield stuff. I have got one wifi shield V3 RPSMA. I need to measure RSSI between a transmitter and a receiver. Would it be possible to do it using two wifi shield ? If possible , how? could you please refer me to some codes or tutorials?
regards,
Khalid
JaneYu HI, RSSI is an advanced value, so you have to use AT command to get RSSI value. Please check the user manual.
When you turn the switch to Arduino, The wifi chip will only communicate with Arduino chip. It won't convert it to USB port.So if you want to use AT command,switch it to the USB side.
And you can try the sample code from wiki to test the wifi shield works or not
JaneYu Yeah, it is different. when you turn the switch to Arduino, The wifi chip will only communicate with Arduino chip. It won't convert it to USB port.
JaneYu yeah i know that, when i switch to Arduino, it only can transmit data to wifi.
when i try send data from wifi to Arduino it always fail. so my problem is Arduino can't receive data from wifi.
it's my code:
void setup() {
Serial.begin(115200);
}
void loop() {
if(Serial.available()>0)
{char inbyte=Serial.read();
Serial.print(inbyte);
//Serial.print("tes wifi");
//delay(1000);
}
}
it's sucseed sending from wifi but at arduino didn't respond. and rx indicator led at arduino never on. its mean data didn't receive to arduino.
Hi, our tech support team have answered you in the forum, have you seen it? I saw this kind of project before. let me take a look.
JaneYu Hi, this wifi shield support webpage configuration which will be more convenient. you can check its wiki page for the tutorial.
JaneYu hai...thanks for your reply
yes...i have check the wiki for thousand times , download the user manual, ask to the forum, looking for the google :(
i have config the wifi shield form the webpage (http://10.10.100.254). i have set the wifi shield and follow the instruction on the wiki...the wifi can connect to our routers...but...it can't solve my probleam...how can control and manage this wifi shield??
i try to follow the example on the wiki..but, it can't solve my probleam too...that's very simple example...not answering the function of the wifi shield...
the arduino have the library to control and manage the wifi shield but, can't working for WiFi Shield V3 RPSMA (802.11b/g/n).
if you have own library or instruction to control and manage this, please help me...
oh yaa... i try to communicate with serial, at-command, but can't solve my probleam...
my probleam is very simple...i just want to turn on/turn off the led over the wifi...that's it...
thanks
